EUP2512
Dual Channel DC-DC Converter for AMOLED
DESCRIPTION
The EUP2512 generates power supply rails for active-matrix
organic light emitting diode (AMOLED) displays. It includes
a step-up DC-DC and an inverting DC-DC converter making
it suitable for battery operated products.
The step-up converter is a high-accuracy power-efficiency
250mA output regulator. It features an internal 0.5
N-MOSFET, 0.6P-MOSFET and 1.4MHz operation
frequency allowing the use of small inductor and capacitors.
The integrated synchronous rectifier allows the true
shutdown of the outputs. An internal digital soft-start
function controls inrush currents. The step-up converter
output can be externally set 4V to 8V.
The inverting converter is a high-accuracy 250mA regulator.
It features an internal 0.4N-MOSFET, 0.5P-MOSFET
and 1.4MHz operation frequency allowing the use of small
inductor and capacitors. Its -6V to -1V output efficiency up
to 80% at 150mA. An internal digital soft-start function
controls inrush currents.
The EUP2512 is available in a small (3mm × 3mm × 0.6mm)
12 pin thin TDFN package and operates over the -40ºC to
+85ºC temperature range.
